Abu Suhail narrated from his father, that he heard Talhah bin ‘Ubaidullah say: “A man from Najd with unkempt hair came to the Messenger of Allah صلی اللہ علیہ وآلہ وسلم he was speaking loudly but his speech could not be understood until he came close. He was asking about Islam. The Messenger of Allah صلی اللہ علیہ وآلہ وسلم said: ‘Five prayers every day and night.’ He said: ‘Do I have to do any more than that? He said: ‘No, not unless you do it voluntarily.’ The Messenger of Allah صلی اللہ علیہ وآلہ وسلم said: ‘Fasting the month of Ramadan.’ He said: ‘Do I have to do any more than that?’ He said: ‘No, not unless you do it voluntarily.’ Then the Messenger of Allah صلی اللہ علیہ وآلہ وسلم told him about Zakah. He said: ‘Do I have to do any more than that?’ He said: ‘No, not unless you do it voluntarily.’ The man left saying, ‘I will not do any more than that or any less. ‘The Messenger of Allah صلی اللہ علیہ وآلہ وسلم tir said: ‘He will succeed, if he is telling the truth.”(Sahih).
